Better split the arguments beforehand: cmd = ["gawk", "-f", "altertime.awk", "-v", "time_offset=4", "-v", "outfile=testdat.sco", "i1.sco"] Now, what do you want to do with the output? Printing it line by line? output = subprocess.Popen(cmd, stdout=subprocess.PIPE).communicate()[0] lines = output.splitlines() for line in lines: print line -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
